New York Sports Club [NYSC] review: overcharging and customer service

I signed up approximately March 27, 2019. While the salesman was going through the sign up process, he offered me a program where I can pay an annual registration fee and then lock in a monthly charge of $9.99. I told him the contract doesn't look like it supports that the rate won't change after a year. He indicated the verbiage regarding the periodic rate changes applies only toward the annual fee. Thinking that made sense, I signed the contract. Low and behold 3 months later the fee jumps to $14.99 per month. When I called to complain, i was told the contract permits periodic monthly rate changes and that they can't do anything about it. I asked for a Manager and was told they are not in. They would not provide a phone number of where I could reach them either. The representative (Mitchel) said he would speak to the manager on my behalf and call me back the next day. Having not heard from him the following day, I went into the club and asked for Mitchel. He indicated that he totally forgot about our conversation and had not done anything about it (great response following a customer complaint). I told him i would wait while he called the manager. He indicated the manager was again mk oy in and couldn't be reached. He suggested I write an email to a generic inbox, so I told him he could feel free to do that or have his boss call me (I already knew from reading everyone's complaints online no one ever responds to emails). I also told him that NYSC should be ashamed of itself, for not giving its employees the ability to waive those fees. At the very least they should take that money out of the pay given to the salesperson who misrepresented the deal. Mitchells response was to give me a form to cancel my membership. I told that was not enough for two reasons: the first is that my annual registration fee was paid on the assumption that our deal would be in place for the year. And secondly, having been strong along for 3 months, I was now no longer eligible for a special sign up offer advertised by the neighborhood's newest sports club LA Fitness, which had just opened up three months prior. I suspect NYSC offered the great $9.99 deal because they had keep customers from going over to LA Fitness. As soon as LA Fitness ended their sign up promotion they jacked up my rates. I have avoided bring up all the other things wrong with the woodmere NYSC facility as it is not related to this specific complaint, but for two of the three months there was no air conditioning on the main floor (keep in mind what the temperatures were like this summer and the smell that would generate in a gym). I didn't complain much because, I figured what could I expect at $9.99 a month.
This place's management and support for its customers is just atrocious bit to say anything of their deceptive sales practices
